Monitor Description
The ECM continuously monitors its own internal circuits. This self-checking ensures that the ECM is functioning properly.
The two CPUs, main and sub, inside the ECM, perform continuous mutual monitoring. If the outputs from the two CPUs differ or deviate from the standard levels, the ECM determines that the internal circuits are malfunctioning. The ECM then illuminates the MIL and sets the DTC.
